By default, the gallery shortcode does not allow to limit the number of images displayed. This makes sense when you for example include all images attached to a post like this:
<pre><code>[gallery id="4"]
</code></pre>
When this plugin is activated, you may use:
<pre><code>[gallery id="4" limit="3"]
</code></pre>
and it will only display three images.
You can also use an offset parameter:
<pre><code>[gallery id="4" limit="3" offset="1"]
</code></pre>
Will display at most three images, starting at the second.
Note that this plugin is a little bit of a hack.
